Objective To investigate the effect of sarcopenia on postoperative complications in patients undergoing pancreaticoduodenectomy（PD）. Methods The data of 225 patients who underwent pancreaticoduodenectomy in the Nanjing Hospital Affiliated to Nanjing Medical University (Nanjing First Hospital) from March 2012 to February 2020 were retrospectively analyzed. The total area of the skeletal muscle was measured by CT images at the level of the third lumbar vertebra for the diagnosis of sarcopenia. The patients were divided into sarcopenia group and non-sarcopenia group. The clinical data and surgical complications were compared between the two groups to explore the relationship between sarcopenia and postoperative complications. Results Compared with the non-sarcopenia group, the patients in the sarcopenia group were older and had lower hemoglobin concentration, lower serum albumin concentration, and higher total bilirubin levels (P<0.05). The incidences of clinically relevant pancreatic fistula (grade B and C fistula), pulmonary infection, atelectasis and hypoxemia in the sarcopenia group were significantly higher than those in the non-sarcopenia group (P<0.05). The length of ICU stay and perioperative mortality in the sarcopenia group were significantly higher than those in the non-sarcopenia group (P<0.05). Multivariate analysis showed that sarcopenia, preoperative total bilirubin level, pancreatic duct diameter and pancreatic texture were independent risk factors for clinically relevant pancreatic fistula (P<0.05). Sarcopenia, intraoperative blood loss and postoperative abdominal infection were independent risk factors for pulmonary complications after PD (P<0.05). Conclusions Sarcopenia is an independent risk factor for increased incidence of clinically relevant pancreatic fistula and pulmonary complications after PD. Strengthening perioperative nutritional therapy and rehabilitation exercise in patients with sarcopenia is of great significance to reduce postoperative complications of PD.
Objective
To investigate the cause, treatment, and prognosis of the postpancreaticoduodenectomy hemorrhage (PPH) .
Method
A total of 779 patients who underwent pancreaticoduodenectomy at Fudan University Shanghai Cancer Center between January 2015 and December 2016 were enrolled, and the data of them were retrospectively analyzed.
Results
Sixteen patients (PPH group) suffered from PPH and 763 patients didn’t suffered from PPH (non-PPH group) of 779 patients. There was no significant difference in the age, gender, type of disease, operative time, blood loss, and ratio of blood transfusion between the 2 groups (P>0.05), but the incidences of pancreatic fistula and delayed gastric emptying, postoperative drainage time, hospital stay, and mortality were all higher or longer in PPH group compared with non-PPH group (P<0.001). Of the 16 PPH patients, early haemorrhage occurred in 3 patients (including 2 patients with gastrointestinal haemorrhage and 1 patient with intra-abdominal haemorrhage) and delayed haemorrhage occurred in 13 patients (including 6 patients with gastrointestinal haemorrhage and 7 patients with intra-abdominal haemorrhage). All the 3 patients with early haemorrhage were cured by surgery. Of the 13 patients with delayed haemorrhage, 5 patients were cured by radiological intervention, 2 patients were cured by endoscopic hemostasis, and 3 patients were cured by conservative treatment, but 3 patients with sentinel bleeding died after interventional embolization+surgery.
Conclusions
The mortality of PPH is high. Surgery is optimal to early haemorrhage and radiological intervention is optimal to delayed haemorrhage, including embolization or covered stent implantation. The sentinel bleeding should be given great attention.
ObjectiveTo compare surgical safety and postoperative efficacy of total mesopancreas excision (TMpE) with pancreaticoduodenectomy (PD) and standard PD (Whipple).MethodsA total of 123 patients underwent PD in the Affiliated Hospital of Southwest Medical University from August 2013 to December 2017 were included, including 47 patients with pancreatic head carcinoma and 76 patients with periampullary carcinoma, then were divided into a TMpE group and a Whipple group respectively. The operative time, intraoperative blood loss, postoperative hospitalization time, postoperative recovery time of gastrointestinal function, postoperative complications, and postoperative survival of patients with the same site between the Whipple group and the TMpE group were retrospectively compared.Results① There were no significant differences in the baseline data between the TMpE group and the Whipple group in the pancreatic head carcinoma and periampullary carcinoma (P>0.05). ② For the patients with pancreatic head carcinoma, there were no significant differences in the operative time, postoperative hospitalization time, and postoperative gastrointestinal function recovery time between the TMpE group and the Whipple group (P>0.05), but the intraoperative blood loss in the TMpE group was significantly higher than that in the Whipple group (P=0.038); For the patients with periampullary carcinoma, the above indexes had no significant differences between the TMpE group and the Whipple group (P>0.05). ③ The total incidence of complications in the TMpE group was significantly higher than that in the Whipple group for the patients with pancreatic head carcinoma (χ2=6.595, P=0.010), which had no significant difference between the TMpE group and the Whipple group for the patients with periampullary carcinoma (P>0.05). ④ The cumulative survival curve in the TMpE group was better than that in the Whipple group for the patients with pancreatic head carcinoma (χ2=9.597, P=0.002), which had no significant difference between the TMpE group and the Whipple group for the patients with periampullary carcinoma (χ2=0.844, P=0.358).ConclusionsFor patients with pancreatic head cancer, comparing with standard Whipple, although TMpE PD increases intraoperative blood loss and overall incidence of complications, it could significantly improve long-term survival and there are no significant differences in postoperative recovery time and operative safety between Whipple and TMpE; For patients with periampullary carcinoma, there are no significant differences in surgical safety, long-term survival rate, and survival time between TMpE and Whipple.
ObjectiveTo analyze risk factors of gastric paralysis following pancreaticoduodenectomy so as to offer help for prevention and treatment of gastric paralysis.
MethodDomestic and international literatures about gastric paralysis following pancreaticoduodenectomy were collected, diagnostic criteria, risk factors, and the latest progress of gastric paralysis were summarized.
ResultsGastric paralysis is one of the most common postoperative complications following pancreaticoduodenectomy. It might be caused by many risk factors, such as operation method, gastrointestinal anastomosis, abdominal complications, chronic hyperglycemia, and excess infusion, etc.
ConclusionsAlthough definition of gastric paralysis by ISGPS is widely adopted, it fails to distinguish gastric paralysis from impaired gastric function related to other postoperative complications and it might result in an overestimation of its true morbidity. The risk factors of occurrence of gastric paralysis are still in controversy and results of research in different centers are not same, more prospective randomized controlled trials are needed.
ObjectiveTo systematically evaluate the effect of different enteral nutrition timing on patients with pancreaticoduodenectomy.MethodsPubMed, Embase, The Cochrane Library, Web of Science, CBM, CNKI, WanFang Data, and VIP databases were searched to collect RCTs for nutritional support in pancreaticoduodenectomy patients. The search time was established until March 1 2019. After two independent investigators conducted literature screening, data extraction, and evaluation of the risk of bias in the included studies, a meta-metabolic analysis was performed using the R 3.5.3 software gemtc package, JAGS 3.4.0, and Revman software.ResultsA total of 8 RCTs were included, for a total of 825 patients. The results of reticular meta-analysis showed that there was no significant difference in the duration of hospitalization for patients with pancreaticoduodenectomy, between the enteral nutrition supported at different timing. The results of the ranking probability map suggested that preoperative enteral nutrition was a better option for supporting nutrition in patients with pancreaticoduodenectomy, secondly, timing to give was 24–48 hours after operation.ConclusionsAccording to the results of mesh meta-analysis and probabilistic ranking, the nutritional status of patients is corrected before surgery, and the effect of enteral nutrition is better than other nutritional support methods. Secondly, enteral nutrition should be given at 24–48 hours after operation in combination with ESPEN and ERAS recommendations.
ObjectiveTo summarize and analyze the long-term clinical effect of duodenum-preserving pancreatic head resection (DPPHR) versus pancreaticoduodenectomy.MethodsThe clinical data of 102 patients who underwent DPPHR (n=35) or pancreaticoduodenectomy (n=67) from January 2014 to December 2019 in The First Affiliated Hospital of Xinjiang Medical University were analyzed retrospectively.ResultsThe operations of patients in the DPPHR group and the PD group were successfully complete, no one died during operation or perioperative period. The weight gain in one year after operation and incidences of exocrine dysfunction in the DPPHR group were all better than those of the PD group (P<0.05), but there was no significant difference on the other complications between the two groups (P>0.05). The pain score, diarrhea score, and the overall health status score in one year after operation significantly improved in the DPPHR group than those in the PD group (P<0.05).ConclusionDPPHR is more beneficial to improve the quality of life after operation, and is a better surgical procedure for benign and low-grade malignant diseases of pancreatic head.
Objective To investigate the risk factors and preventions of functional delayed gastric emptying (FDGE) after pylorus-preserving pancreatoduodenectomy (PPPD). Methods The clinical data of 41 patients after undergoing PPPD between 2003 and 2009 in this hospital were analyzed retrospectively.Results In all 41 cases, postoperative complications developed in 13 patients (31.7%), in which 7 patients developed FDGE (17.1%). The complications excluding FDGE (P=0.010) and diabetes (P=0.024) had remarkable relations with the FDGE in the univariate analysis; Compared with the non-FDGE patients, the albumin was declined obviously (P=0.020) while the serum direct bilirubin increased significantly (P=0.036) in the FDGE patients, while the development of FDGE had relation only with the albumin (P=0.039) and the complication of diabete (P=0.047) by the binary logistic regression analysis. Conclusion In the patients undergoing PPPD, preoperative control of the blood glucose, preoperative correction of hypoproteinemia and hyperbilirubinemia, and centralizing PPPD in high-volume have possibly positive significance for the prevention of FDGE.
ObjectiveTo understand the adverse effects of perioperative red blood cells (RBC) transfusion on patients after pancreaticoduodenectomy (PD) so as to provide ideas for reducing postoperative complications and improving prognosis. MethodThe relevant literatures at home and abroad in recent years about studies of perioperative RBC transfusion on postoperative complications (focusing on pancreatic fistula and infection) and prognosis of patients with PD were reviewed. ResultsThe rates of postoperative complications and perioperative RBC transfusion after PD were still higher. The perioperative RBC transfusion might increase the rate of postoperative complications, promote early tumor recurrence, and shorten the disease-free survival and overall survival. At present, with the progress of technology, the perioperative RBC transfusion rate was decreasing. At the same time, with the accelerated development of new blood transfusion technologies such as freeze-drying and refrigeration, the decline rate was still expected to be increased. ConclusionsPerioperative RBC transfusion in PD might have adverse effects on postoperative complications and prognosis. Although further research is still needed to explore its necessary connection, this adverse effect needs to be paid enough attention in clinical practice. Early identification of risk factors, strict transfusion indications and minimizing amount or concentration of RBC transfusion might help to avoid or reduce RBC transfusion and minimize its adverse effects.
Objective To analyze the effect of inner diameter of pancreatic duct following pancreaticoduodenectomy on pancreatic fistula. Methods From January 1995 to December 2008, 256 patients underwent pancreaticoduodenectomy were divided into four groups based on the types of pancreaticojejunostomy: end-to-side “mucosa-to-mucosa” anastomosis group (n=115), end-to-end “mucosa-to-mucosa” anastomosis group (n=71), end-to-end invaginated pancreaticojejunostomy group (n=43) and pancreaticogastrostomy group (n=27). Alternatively, 238 patients were divided into two groups according to drainage ways: stenting tube for internal drainage group (n=132) and stenting tube for external drainage group (n=106). Furthermore, 233 cases were divided into three groups on the basis of inner diameter of pancreatic duct: ≤0.2 cm group (n=54), 0.2-0.4 cm group (n=93) and ≥0.4 cm group (n=76). Then, the incidence rate of pancreatic fistula of each group was compared. Results The incidence of pancreatic fistula was 8.20% (21/256). The incidence of pancreatic fistula for different types of pancreaticojejunostomy was as follow: end-to-side “mucosa-to-mucosa” anastomosis group (7.83%， 9/115), end-to-end “mucosa-to-mucosa” anastomosis group (7.04%, 5/71), end-to-end pancreaticogastrostomy invaginated group (13.95%, 6/43) and pancreaticogastrostomy group (3.70%, 1/27), in which there wasn’t significant difference in 4 groups （χ2=2.763，P=0.430）. There was no significant difference of the incidence of pancreatic fistula between stenting tube for internal drainage group (9.10%, 12/132) and stenting tube for external drainage group (8.49%, 9/106), χ2=0.126, P=0.722. The incidence of pancreatic fistula in ≥0.4 cm group, 0.2-0.4 cm group and ≤0.2 cm group was respectively 0, 15.05% (14/93) and 11.11%(6/54), and the difference was significant (χ2=12.009, P=0.002). No correlation was found between the incidence of pancreatic fistula of different inner diameter of pancreatic duct and the types of pancreaticojejunostomy (χ2=1.878， P=0.598). Conclusion The inner diameter of pancreatic duct is an important factor for postoperative pancreatic fistula. No relationship is found between the types of pancreaticojejunostomy and pancreatic fistula in this study.
Objective To explore the effects of recombinant human growth hormone （rhGH） on senile patients after pancreaticoduodenectomy. MethodsFortysix patients were divided into the therapeutic group (rhGH, n=17) and control group (n=29). Both were treated with parenteral nutrition. In the therapeutic group, rhGH (8 u/d) was given hypodermically for 7 days. After operation the levels of albumin, prealbumin, transferrin, and immunoglobulin were measured. Postoperative fatigue syndrome and the average length of stay in hospital were observed too. ResultsAfter operation the levels of albumin, prealbumin, transferrin, and immunoglobulin in the therapeutic group were significantly higher than those of control group. The degree of postoperative fatigue syndrome in the therapeutic group was less than that of control group. The average length of stay in hospital was significantly shortened. Conclusion The early application of rhGH in senile patients after pancreaticoduodenectomy can enhance immune function, reduce the incidence of infection, promote the postoperative recovery, shorten the average length of stay in hospital,decrease the mortality, increase the safety of operation and improve the postoperative life quality of senile patients.
